Be it known that I, REUBEN A. MCCAULEY, of the city and county ofBaltimore, in the State of Maryland, have invented a new and improvedPump; and I do hereby declare ythatvthey following isa full and exactdescription thereof, reference being had to the accompanying drawing,andto the letters of reference marked thereon. The nature ofmy'invention consists .in the peculiar construction of aidouble-actingsubmerged pump, to raise and force water` or other; liquids. Y

To enable others skilled in the art to make and'use my invention, Iwill4proceed to describe its construction and operation. i Y

In the drawingsA represents pump proper, B' a central chamber, in whichthe piston-rod, C, and its hollow cylindrical head, lll-play. On eachside of` this chamber'there are others', E an'd F, which may-beef anydesira ble shape and .size to bring about economy and a proper workingof the pump. The partA is securedvin any suitable'way, say' by bolts,screws, nuts, 8vo., to its bottom plate, a, to which is attached astrainer, b, having a; chamber, o?. Through pla-te Aa there are twoopenings, e and f, over which are two valves, g and'h. In the top partof A, or its to-p plate p, there is an opening, i, for the piston-rod topass through it has a neck, G', as a guide for the working of' thepiston. There are also two other openings, fand le, in the 'aforesaidplate p, over which, also, are two valves, Z' and m, which open into achamber, H, part of an upper metallic connection, I', to be secured to Aby bolts, screws, nuts, &c. Into this is iitted a woodenpipe, J; it maybe a metal one, if desired.- At the joints of .each section of 5,1 put ametal sleeve, 11:-, having a. projection, o, through' which there is anopening, q, to guide the rod K, which is' a continuation of piston-mdc;this rod extending upwards, and' connecting with any suitable leveror-rock-shaft, crank, Ste., care being taken to give suitable play forsaid rod K. The sleeves n perform two oices. They secure the jointsv andhold the sectionsv togetheniandf are guides to rod K. They may be soconstructed, in being adjusted, as to have' a strong binding eieet o-n.the upper and lower ends of adjacent sections. Through the upper end'of central cylinder B there isy an opening, as shown at r, and at thebottom of it there is another, s. i

The operationof thepulnpis as follows In the drawing the piston isrepresented as descending, hencel valve I1. is down, closing hole f,whilst the water in B is vforced through s upchamber F, and out of la,opening valve m into chamber H or stock tube J. This also shuts downvalve l, andl opens valve g, ietting the water.

into the other chamber, When the movement of the piston is reversed, orgoes up, valve m shuts down, zis opened, g also closes, and l opens,audthe iiuid in E and top part of Bfis forced through 7' into H, thuscausing, on'each stroke, a How through tube J. The upper works of pumpneed no description.- The advantages of the construction of myinvention, as to economy and eicient working, are too obvious to needcomment.

Having thus: described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is l i l 1. The pump A,with its. side chambers E and F, piston chamber B, openings o and r,receivingand discharging .ports e, f, j, and 7c, arranged, constructed',and operating in the manner substantially as shown and described, andfor the purpose set forth. v i

v2, In combination with said pump, the pipe J and the connecting guidesleeves ln, coi1str'ucted, arranged, and operating in the mannersubstantially as Shownl andA described, and for the purposes set forth.
